What is the greatest common factor of 21 42 49?
To find the greatest common factor of 21, 42, and 49, we first need to find the prime factors of each number. The prime factors of 21 are 3 and 7, the prime factors of 42 are 2, 3, and 7, and the prime factors of 49 are 7 and 7. The greatest common factor is the product of the common prime factors raised to the lowest power they appear in any of the numbers, which in this case is 7. Therefore, the greatest common factor of 21, 42, and 49 is 7.
What is the greatest common factor of 21 49 and 63?
To find the greatest common factor (GCF) of 21, 49, and 63, we first need to find the prime factorization of each number. The prime factorization of 21 is 3 x 7, 49 is 7 x 7, and 63 is 3 x 3 x 7. The GCF is the product of the common prime factors raised to the lowest power they appear in all the numbers, which in this case is 7. Therefore, the GCF of 21, 49, and 63 is 7.
What is the HCF of 21 and 49?
The first step when finding an HCF is to break the numbers down into their prime factors. In this case we get: 21 = 3x7 49 = 7x7 The next step is to identify any common prime factors. In this case both numbers have a 7 as a prime factor. There are no more common prime factors, and thus the HCF of 21 and 49 is 7.
What is the least common multiple of 21 48 and 49?
The least common multiple of the numbers 21, 48 and 49 is 2,352.
What are factors of 147?
The factors of 147 are 1, 3, 7, 21, 49, and 147.
What is the factor of 21 and 49?
Factors or 21 are: 1 3 7 21 Factors or 49 are: 1 7 49 Common factors of 21 and 49 are: 1 and 7
The factors of 49 21 and 91?
Do you mean, what are the common factors of 49, 21, and 91? Only 7 (and 1, of course) is a common factor for those numbers. Individually, 49's factors are 1, 7 and itself. 21's factors are 1, 3, 7, and itself. 91's factors are 1, 7, 13, and itself.
What are the factors for 21 35 and 49?
Factors of 21 are 3 and 7 (21=3x7). Factors of 35 are 5 and 7 (35=5x7). Factors of 49 are 7 and 7 (49=7x7).
What is a Greatest Common Factor of 21 and 49?
The factors of 21 are 1, 3, 7, 21 The factors of 49 are 1, 7, 49 The largest matching number is 7 so 7 is the GCF of 21 and 49.
What are the factor of 21 and 49?
the factors of 21 are 3,7,1, 21,and -1, -21,-3,-7. the factors of 49 are 1,49,7,7 and -1, -21-7-7.
What is the greatest common factor of 91 21 and 49?
The greatest common factor (GCF) of three numbers is the largest number that divides each of the three numbers without leaving a remainder. To find the GCF of 91, 21, and 49, we need to factorize each number. The prime factors of 91 are 7 and 13, the prime factors of 21 are 3 and 7, and the prime factors of 49 are 7 and 7. The common factor among them is 7, so the GCF of 91, 21, and 49 is 7.
Which numbers divide evenly into 147?

What are the the factors of 49?
1,7, and 49 are the factors of 49Factors are numbers that can be divided from a certain number. Factors of 49 can be worked out by multiplying different numbers with another number.1, 7, and 49.
What are the common factors for 21 and 49?
The factors of 21 are:1, 3, 7, 21The factors of 49 are:1, 7, 49The common factors are:1, 7
Is 8 a factor of 49?
No, the only factors of 49 are 1, 7, and 49. Therefore, 8 and 5 are not factors of 49.
What numbers are the factors of 49?
1, 7, & 49
What is the greatest common factor of 21 49 and 63?
To find the greatest common factor (GCF) of 21, 49, and 63, we first need to find the prime factorization of each number. The prime factorization of 21 is 3 x 7, 49 is 7 x 7, and 63 is 3 x 3 x 7. The GCF is the product of the common prime factors raised to the lowest power they appear in all the numbers, which in this case is 7. Therefore, the GCF of 21, 49, and 63 is 7.
